Solving the Teukolsky equation with physics-informed neural networks
Raimon Luna, Juan Calderón Bustillo, Juan José Seoane Martínez +2
We use physics-informed neural networks (PINNs) to compute the first quasi-normal modes of the Kerr geometry via the Teukolsky equation. This technique allows us to extract the com…
Kicks in charged black hole binaries
Raimon Luna, Gabriele Bozzola, Vitor Cardoso +2
We compute the emission of linear momentum (kicks) by both gravitational and electromagnetic radiation in fully general-relativistic numerical evolutions of quasi-circular charged…
Addendum to "Strong cosmic censorship: The nonlinear story"
Raimon Luna, Miguel Zilhão, Vitor Cardoso +2
We clarify a number of issues that arise when extending the analysis of Strong Cosmic Censorship (SCC) to perturbations of highly charged Reissner-Nordström de Sitter (RNdS) spacet…
Challenges to global solutions in Horndeski's theory
Laura Bernard, Luis Lehner, Raimon Luna
We explore the question of obtaining global solutions in Horndeski's theories of gravity. Towards this end, we study a relevant set of the theory and, by employing the Einstein fra…
Strong cosmic censorship: The nonlinear story
Raimon Luna, Miguel Zilhão, Vitor Cardoso +2
A satisfactory formulation of the laws of physics entails that the future evolution of a physical system should be determined from appropriate initial conditions. The existence of…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
